Jet aircraft, carrier task forces and tanks consume vast amounts of fossil fuel--while emitting vast amounts of greenhouse gases. The Pentagon’s carbon footprint is bigger than those of many entire nations. Now, it’s caught in the middle. It’s a massive contributor to climate change, which is threatening its mission worldwide. Seaports and airstrips are being flooded or burned out, and restoring operations costs many millions of dollars.
Meantime, environmental damage is leading to instability and the prospect of international violence. Water shortages have increased tensions in the Middle East and caused new hostilities between India and Pakistan, two nuclear powers. Russia and China are taking advantage of changing conditions. Will politicians who scorn environmentalists and mistrust climate scientists listen to the warnings of military leaders?

Since March some 387 Boeing 737 Max jets have been grounded by regulators and airlines with no end in sight. Boeing profits have tanked. Last month the company recorded its biggest ever quarterly loss and deliveries are at their lowest since 2012. Boeing says it expects the plane to return to service by the end of this year, as it continues to focus on the plane’s software system, thought to be the cause of both plane crashes. Boeing’s crisis highlights a problem beyond flight safety. The aircraft manufacturer chose to prioritize big spending on CEO compensation and stock buybacks rather than reinvest profits on its employees, infrastructure and R and D. Last year alone, Boeing’s chief executive Dennis Muilenburg took home $30 in compensation and gains from options. Buybacks over investment; the financial strategy that’s great for shareholders but may well have cost Boeing the public’s trust.
